The wardens of Region 1 and 3 set off to educate the public on Montana's aquatic invasive species population. Meanwhile, a tribute is made for one of Montana's honorary wardens.

Wardens stumble upon a heated situation on the side of the road; Lesofski searches for the culprit behind an elk carcass; a riverside check station cites four minors under the influence; underage drivers are caught behind the wheel.
